Description

Technical Field

[0001] This invention relates to the field of carbon emission technology, and in particular to a carbon information calculation system for carbon emission streams. Background Technology

[0002] Carbon emission flows in a power system are a virtual network flow that is coupled with the power flow and moves in a directional manner with the active power flow of the system.

[0003] Current carbon emission flow calculations in power systems are generally based on carbon meter systems. These systems consist of a central server, carbon meters distributed across different locations within the power system, and communication lines connecting the meters to the central server. The carbon meters collect the data needed for emission flow calculations and transmit it to the central server via these communication lines, enabling the central server to perform the calculations. This method of transmitting all collected data to the central server for calculation places a heavy burden on the server, causing slow response times. Therefore, reducing the data processing load on the central server is a pressing issue that needs to be addressed. Summary of the Invention

[0004] The present invention provides a carbon emission flow calculation system that can establish a correspondence between auxiliary servers and power supply branches, and then perform distributed calculation of carbon information. This solves the problem of the heavy burden and slow calculation speed of the existing technology where carbon information is centrally calculated by a central server, and improves the calculation speed of carbon information.

[0005] An embodiment of the present invention provides a carbon information calculation system for carbon emission streams, comprising: a central server, several auxiliary servers, and several carbon meters distributed in different locations in the power system;

[0006] The carbon table is used to collect the carbon table data required for calculating carbon information in the current carbon table.

[0007] The central server is used to determine several power supply branches based on the location of each carbon meter in the power system and the direction of the current in the carbon meter; and to establish a one-to-one correspondence between each power supply branch and each auxiliary server.

[0008] Each of the auxiliary servers is configured to determine the corresponding power supply branch to be calculated based on the correspondence; obtain the carbon meter data of each carbon meter in the power supply branch to be calculated; and calculate the carbon information of the power supply branch to be calculated based on the carbon meter data.

[0009] Furthermore, the determination of several power supply branches based on the location of each carbon meter in the power system and the current direction of the carbon meters includes:

[0010] Based on their location in the power system, carbon meters are classified into: generation-side carbon meters for collecting data from power plants, network-side carbon meters for collecting data from transmission lines, and user-side carbon meters for collecting energy consumption information from users.

[0011] Each carbon meter is assigned a grade based on its relevance to the power plant; the higher the relevance to the power plant, the higher the grade assigned to the carbon meter.

[0012] The electrical transmission lines between carbon meters are determined based on the grade of each carbon meter and the direction of the current in each carbon meter.

[0013] Several power supply branches are determined based on the grade of each carbon meter and the electrical transmission lines between the carbon meters.

[0014] Furthermore, the carbon table is used to collect the carbon table data required for calculating carbon information, including:

[0015] If the carbon meter is a power generation side carbon meter, the collected carbon meter data includes: first energy data for energy consumed by the power plant, first emission coefficient for energy consumed by the power plant, and first active power injected into the power plant.

[0016] If the carbon meter is a network-side carbon meter, the collected carbon meter data includes: the second active power connected to the upstream carbon meter of the network-side carbon meter and the carbon flow density connected to the upstream carbon meter of the network-side carbon meter.

[0017] If the carbon meter is a user-side carbon meter, the collected carbon meter data includes: the second energy data of the user's electricity consumption and the second emission coefficient of the user's electricity consumption.

[0018] Furthermore, the calculation of the carbon flux density connected to the upstream carbon meter of the network-side carbon meter includes:

[0019] The carbon flow density connected to the upstream carbon meter of the network-side carbon meter is calculated using the following formula:

[0020]

[0021] Among them, e Ni I represents the carbon potential of node i, where the i-th network-side carbon table is located. + Let P represent the set of all electrical transmission lines that inject power into node i, where the i-th network-side carbon table is located. BS P represents the second active power connected to the power transmission line S. Gi e represents the first active power injected by the power plant into node i, where the i-th network-side carbon meter is located. Gi Let i be the carbon emission intensity of the generator unit of the power plant, where i is an integer greater than or equal to 1.

[0022] Further, the carbon meter data of each carbon meter in the power supply branch to be calculated is obtained, and the carbon information of the power supply branch to be calculated is calculated based on the carbon meter data, including:

[0023] When the carbon meter data of the power supply branch to be calculated is the carbon meter data of the power generation side carbon meter, the carbon emission intensity of the power plant in the power supply branch to be calculated is calculated based on the first energy data and the first emission coefficient.

[0024] When the carbon meter data of the power supply branch to be calculated is the carbon meter data of the network-side carbon meter, the carbon flow density of the network-side carbon meter in the power supply branch to be calculated is calculated based on the carbon emission intensity, the first active power, the second active power and the carbon flow density connected to the upstream carbon meter of the network-side carbon meter.

[0025] When the carbon meter data of the power supply branch to be calculated is the carbon meter data of the user-side carbon meter, the carbon emissions of the user-side in the power supply branch to be calculated are calculated based on the second energy data and the second emission coefficient.

[0026] The carbon information of the power supply branch to be calculated is determined based on the carbon emission intensity of the power plant in the power supply branch to be calculated, the carbon flow density of the carbon meter on the network side, and the carbon emission amount on the user side.

[0027] Furthermore, it also includes: an electricity meter that corresponds one-to-one with each carbon meter;

[0028] Each of the aforementioned meters is used to collect the current direction of the corresponding carbon meter.

[0029] Furthermore, the auxiliary server is also used for:

[0030] The carbon information of the power supply branch to be calculated is transmitted to the central server so that the central server can update the carbon information in the power system.

[0031] The following benefits can be obtained by implementing the present invention:

By establishing the correspondence between auxiliary servers and power supply branches, the calculation speed of carbon information for each power supply branch is improved. At the same time, using auxiliary servers for branch calculations avoids centralized data calculation on the central server, reducing the computational burden on the central server.

It should be understood that these drawings depict only some embodiments disclosed in this application and should not be construed as limiting the scope of this application.

[0034] Figure 1 This is a schematic diagram of a carbon meter system provided in an embodiment of the present invention.

[0035] Figure 2 This is a schematic diagram of the structure of a carbon information calculation system for carbon emission streams provided in an embodiment of the present invention. Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figure 1 As shown, a carbon meter system in the prior art consists of a central server, carbon meters distributed in different locations in the power system, and communication lines connecting each carbon meter and the central server. The carbon meters are used to collect data information required for carbon emission flow calculation and transmit it to the central server through the communication lines, so that the server can calculate the carbon emission flow based on the data information.

[0038] In existing carbon meter systems, carbon emission flow calculations rely on a single central server based on collected carbon meter data. This means the central server must process massive amounts of data, placing a significant burden on it and resulting in slow computation speeds. Consequently, the update frequency of carbon information in the associated power system decreases. Furthermore, the centralized processing method means that a central server failure can disrupt overall carbon emission flow calculations, hindering timely updates of carbon information.

[0039] To address the problems existing in the prior art, this invention proposes a carbon information calculation system for carbon emission streams.

[0040] like Figure 2 The figure shown is a carbon information calculation system for carbon emission streams provided in an embodiment of the present invention, including: a central server, several auxiliary servers and several carbon meters distributed in different locations of the power system;

[0041] The carbon table is used to collect the carbon table data required for calculating carbon information in the current carbon table.

[0042] The central server is used to determine several power supply branches based on the location of each carbon meter in the power system and the direction of the current in the carbon meter; and to establish a one-to-one correspondence between each power supply branch and each auxiliary server.

[0043] Each of the auxiliary servers is configured to determine the corresponding power supply branch to be calculated based on the correspondence; obtain the carbon meter data of each carbon meter in the power supply branch to be calculated; and calculate the carbon information of the power supply branch to be calculated based on the carbon meter data.

[0044] Specifically, the carbon emission flow calculation system includes multiple auxiliary servers, a central server, and multiple carbon meters distributed across different locations within the power system. A two-way communication relationship is established between the central server, the multiple auxiliary servers, and the multiple carbon meters. This system is built upon the power system and the carbon meter system. In this system, the carbon meter data collected by each carbon meter for calculating carbon information is processed by the central server. After determining multiple power supply branches based on the location of each carbon meter in the power system and the direction of the current in the carbon meters, the central server proposes a correspondence between these power supply branches and the multiple auxiliary servers. This allows each auxiliary server to calculate the carbon information corresponding to each carbon meter within its designated power supply branch.

[0045] In a preferred embodiment, determining several power supply branches based on the location of each carbon meter in the power system and the current direction of the carbon meters includes: classifying the carbon meters into: generation-side carbon meters for collecting data information from power plants, network-side carbon meters for collecting data information from transmission lines, and user-side carbon meters for collecting energy consumption information from users; assigning a grade to each classified carbon meter based on its correlation with the power plant; wherein, the higher the correlation with the power plant, the higher the grade assigned to the carbon meter; determining the electrical transmission lines between the carbon meters based on their grades and the current direction of each carbon meter; and determining several power supply branches based on their grades and the electrical transmission lines between the carbon meters.

[0046] In another preferred embodiment, there is an electricity meter corresponding to each carbon meter; each of the electricity meters is used to collect the current direction of the corresponding carbon meter.

[0047] Specifically, in a power system, there are typically nodes representing power plants, nodes representing users, and some intermediate nodes. Based on these nodes required by the power system, they are replicated in the carbon emission flow calculation system, and the direction of carbon flow is determined accordingly. Figure 2 The positions of each carbon meter in the system are shown. Based on the position of each carbon meter... Figure 2The carbon meters are categorized based on their location within the network. For example, carbon meters connected to power plants and used to collect data from power plants are called power generation-side carbon meters; carbon meters connected to users and used to collect energy consumption information from users are called user-side carbon meters; and intermediate carbon meters located between power generation-side and user-side carbon meters are called network-side carbon meters, which are used to collect data from transmission lines.

[0048] Simultaneously, when classifying carbon meters, each carbon meter is assigned a grade based on its correlation with the power plant. Since the generation-side carbon meter has the highest correlation with the power plant and is closest to it, it has the highest grade. The user-side carbon meter has the lowest correlation with the power plant and is furthest from it, so it is assigned the lowest grade. The network-side carbon meter has a lower correlation with the power plant than the generation-side carbon meter but a higher correlation than the user-side carbon meter. Therefore, the final grade ranking from high to low is: generation-side carbon meter, network-side carbon meter, and user-side carbon meter.

[0049] By determining the carbon meter rating, from high to low, and combining this with the corresponding current direction of the carbon meter, multiple power supply branches can be identified. For example, in... Figure 2 In this system, the highest-level carbon meter is the generator-side carbon meter, and the lowest-level carbon meter is the user-side carbon meter. There are four identifiable power supply branches between the generator-side and user-side carbon meters: L1: Generator-side carbon meter 1 → Network-side carbon meter 1 → Network-side carbon meter 2 → Network-side carbon meter 3 → User-side carbon meter 1; L2: Generator-side carbon meter 1 → Network-side carbon meter 1 → Network-side carbon meter 2 → Network-side carbon meter 3 → User-side carbon meter 2; L3: Generator-side carbon meter 1 → Network-side carbon meter 1 → Network-side carbon meter 2 → Network-side carbon meter 3 → User-side carbon meter 3; L4: Generator-side carbon meter 2 → Network-side carbon meter 4 → User-side carbon meter 4. Each power supply branch is calculated by a corresponding auxiliary server, enabling faster calculation of carbon information for each power supply branch.

[0050] Preferably, when multiple power supply branches share a common intermediate carbon meter, the carbon information of each power supply branch sharing the intermediate carbon meter can be directly calculated by a single server. For example, if L1-L3 share a network-side carbon meter 3, to avoid duplicate calculations of the carbon information for network-side carbon meter 3, L1-L3 can be treated as a single power supply branch, and the carbon information for L1-L3 can be calculated by the same auxiliary server. This reduces the number of auxiliary servers required while maintaining calculation speed, which helps reduce costs while achieving distributed data processing.

[0051] In a preferred embodiment, the carbon meter is used to collect carbon meter data required for calculating carbon information, including: if the carbon meter is a power generation-side carbon meter, the collected carbon meter data includes: first energy data for energy consumed by the power plant, first emission coefficient for energy consumed by the power plant, and first active power injected into the power plant; if the carbon meter is a network-side carbon meter, the collected carbon meter data includes: second active power connected to the upstream carbon meter of the network-side carbon meter and carbon flow density connected to the upstream carbon meter of the network-side carbon meter; if the carbon meter is a user-side carbon meter, the collected carbon meter data includes: second energy data for user electricity consumption and second emission coefficient for user electricity consumption.

[0052] Specifically, carbon meters in different locations serve different purposes. Therefore, each carbon meter collects data based on its current location, depending on its type. For example, the carbon meter data collected by the power generation side carbon meter includes at least: the first energy data for energy consumed by the power plant, the first emission factor for energy consumed by the power plant, and the first active power injected into the power plant. The data listed in this embodiment only describes the minimum data required to satisfy carbon information calculation. When other calculations are required, the carbon meter can collect the remaining unmentioned data.

[0053] After the power supply branch is determined and each carbon meter completes its own carbon meter data collection, each auxiliary server matches its corresponding power supply branch to be calculated and obtains the carbon meter data of each carbon meter contained in the power supply branch to be calculated, thereby completing the carbon information calculation for the corresponding power supply branch to be calculated. Specifically, the carbon meter data of each carbon meter in the power supply branch to be calculated can be sent to the auxiliary server through a pre-established communication method.

[0054] In a preferred embodiment, acquiring carbon meter data from each carbon meter in the power supply branch to be calculated, and calculating carbon information of the power supply branch to be calculated based on the carbon meter data, includes: when the carbon meter data of the power supply branch to be calculated is the carbon meter data of the generation-side carbon meter, calculating the carbon emission intensity of the power plant in the power supply branch to be calculated based on the first energy data and the first emission coefficient; when the carbon meter data of the power supply branch to be calculated is the carbon meter data of the network-side carbon meter, calculating the carbon flow density of the network-side carbon meter in the power supply branch to be calculated based on the carbon emission intensity, the first active power, the second active power, and the carbon flow density connected to the upstream carbon meter of the network-side carbon meter; when the carbon meter data of the power supply branch to be calculated is the carbon meter data of the user-side carbon meter, calculating the carbon emissions on the user side in the power supply branch to be calculated based on the second energy data and the second emission coefficient; and determining the carbon information of the power supply branch to be calculated based on the carbon emission intensity of the power plant, the carbon flow density of the network-side carbon meter, and the carbon emissions on the user side in the power supply branch to be calculated.

[0055] Specifically, the carbon information of the power supply branch to be calculated is performed based on the carbon meters contained in the branch. For example, when calculating the carbon information of L4: generator-side carbon meter 2 → network-side carbon meter 4 → user-side carbon meter 4, the carbon meter data of the corresponding generator-side carbon meter 2, network-side carbon meter 4, and user-side carbon meter 4 need to be collected separately, and the following calculations need to be performed:

[0056] Step S1: Calculate the carbon emission intensity of the power plant adjacent to the power generation side carbon meter 2 based on the first energy data collected by the power generation side carbon meter 2 and the first emission coefficient.

[0057] Step S2: Calculate the carbon flow density of the network-side carbon meter 4 based on the carbon emission intensity of the power plant adjacent to the power generation side carbon meter 2, the first active power injected into the power plant adjacent to the power generation side carbon meter 2, the second active power connected to the upstream carbon meter of the network-side carbon meter 4, and the carbon flow density connected to the upstream carbon meter of the network-side carbon meter 4; in this embodiment, the upstream carbon meter of the network-side carbon meter 4 is the power generation side carbon meter 2.

[0058] In a preferred embodiment, the calculation of the carbon flow density of the upstream carbon meter connected to the network-side carbon meter includes: calculating the carbon flow density of the upstream carbon meter connected to the network-side carbon meter using the following formula:

[0059]

[0060] Wherein, the carbon flux density of the network-side carbon table is the carbon potential of the nodes where multiple upstream carbon tables are located, e Ni I represents the carbon potential of node i, where the i-th network-side carbon table is located. + Let P represent the set of all electrical transmission lines that inject power into node i, where the i-th network-side carbon table is located. BS P represents the second active power connected to the power transmission line S. Gi e represents the first active power injected by the power plant into node i, where the i-th network-side carbon meter is located. Gi Let i be the carbon emission intensity of the generator unit of the power plant, where i is an integer greater than or equal to 1.

[0061] Step S3: Calculate the carbon emissions of the user side connected to the user side carbon meter 4 based on the second energy data of user electricity consumption and the second emission coefficient of user electricity consumption collected by the user side carbon meter 4.

[0062] The carbon emission intensity of the power plant adjacent to the carbon meter 2 on the power generation side, the carbon flow density of the carbon meter 4 on the network side, and the carbon emission of the user side connected to the carbon meter 4 on the user side can be obtained by the above three steps. The information obtained constitutes the carbon information of the power supply branch L4.

[0063] In a preferred embodiment, the auxiliary server is further configured to: transmit the carbon information of the power supply branch to be calculated to the central server, so that the central server updates the carbon information in the power system.

[0064] Specifically, after the auxiliary server completes the carbon information calculation for the corresponding power supply branch, the carbon information of the calculated power supply branch can be transmitted to the central server to facilitate the updating of carbon information.

[0065] By implementing the above-mentioned scheme proposed in this invention, through the data information transmission between the carbon meter and the central server, and the data information transmission between the central server and the auxiliary servers, each auxiliary server can calculate the carbon information of the corresponding parallel branch based on the received data information, which can effectively reduce the computational load of the central server.
